A compact open-weight base model from LAION, trained on 160 billion tokens with a relatively small learning rate, then fine-tuned via supervised fine-tuning. At 7 billion parameters, it sits in a familiar size range — capable enough for many language tasks but constrained by its 4096-token context window. The specific training corpus (wc386k) and SFT process shape its behavior, though detailed capability benchmarks aren't widely documented.
